PART 36_LICENSES AND RADIATION SAFETY REQUIREMENTS FOR IRRADIATORS
--Table of Contents
 
      Subpart C_Design and Performance Requirements for Irradiators
 
Sec. 36.41  Construction monitoring and acceptance testing.

    The requirements of this section must be met for irradiators whose 
construction begins after July 1, 1993. The requirements must be met 
prior to loading sources.
    (a) Shielding. For panoramic irradiators, the licensee shall monitor 
the construction of the shielding to verify that its construction meets 
design specifications and generally accepted building code requirements 
for reinforced concrete.
    (b) Foundations. For panoramic irradiators, the licensee shall 
monitor the construction of the foundations to verify that their 
construction meets design specifications.
    (c) Pool integrity. For pool irradiators, the licensee shall verify 
that the pool meets design specifications and shall test the integrity 
of the pool. The licensee shall verify that outlets and pipes meet the 
requirements of Sec. 36.33(b).
    (d) Water handling system. For pool irradiators, the licensee shall 
verify that the water purification system, the conductivity meter, and 
the water level indicators operate properly.
    (e) Radiation monitors. For all irradiators, the licensee shall 
verify the proper operation of the monitor to detect sources carried on 
the product conveyor system and the related alarms and interlocks 
required by Sec. 36.29(a). For pool irradiators, the licensee shall 
verify the proper operation of the radiation monitors and the related 
alarm if used to meet Sec. 36.59(b). For underwater irradiators, the 
licensee shall verify the proper operation of the over-the-pool monitor, 
alarms, and interlocks required by Sec. 36.29(b).
    (f) Source rack. For panoramic irradiators, the licensee shall test 
the movement of the source racks for proper operation prior to source 
loading; testing must include source rack lowering due to simulated loss 
of power. For all irradiators with product conveyor systems, the 
licensee shall observe and test the operation of the conveyor system to 
assure that the requirements in Sec. 36.35 are met for protection of 
the source rack and the mechanism that moves the rack; testing must 
include tests of any limit switches and interlocks used to protect the 
source rack and mechanism that moves the rack from moving product 
carriers.
    (g) Access control. For panoramic irradiators, the licensee shall 
test the completed access control system to assure that it functions as 
designed and

that all alarms, controls, and interlocks work properly.
    (h) Fire protection. For panoramic irradiators, the licensee shall 
test the ability of the heat and smoke detectors to detect a fire, to 
activate alarms, and to cause the source rack to automatically become 
fully shielded. The licensee shall test the operability of the fire 
extinguishing system.
    (i) Source return. For panoramic irradiators, the licensee shall 
demonstrate that the source racks can be returned to their fully 
shielded positions without offsite power.
    (j) Computer systems. For panoramic irradiators that use a computer 
system to control the access control system, the licensee shall verify 
that the access control system will operate properly if offsite power is 
lost and shall verify that the computer has security features that 
prevent an irradiator operator from commanding the computer to override 
the access control system when it is required to be operable.
    (k) Wiring. For panoramic irradiators, the licensee shall verify 
that the electrical wiring and electrical equipment that were installed 
meet the design specifications.
